  • Publication number: 20210142934
    Abstract: A Fe—Ni alloy powder has a small particle diameter, can achieve high ?? in a high frequency band, and has high heat resistance. The Fe—Ni alloy powder can be obtained in such a manner that an acidic aqueous solution containing a trivalent Fe ion and a Ni ion is neutralized with an alkali aqueous solution in the presence of a phosphorus-containing ion. This provides a slurry of a precipitate of a hydrated oxide. Then, a silane compound is added to the slurry to coat the precipitate of the hydrated oxide with a hydrolyzate of the silane compound. The precipitate of the hydrated oxide after coating is recovered through solid-liquid separation. The recovered precipitate is heated to provide iron particles coated with a silicon oxide, and then the silicon oxide coating is removed through dissolution.

  • Patent number: 9969678
    Abstract: In a method of producing an optically active ?-aminocarbonyl compound using a column reactor, a column for a column reactor is charged with asymmetric catalyst particles to form a column reactor. Compounds for a Mannich-type reaction are introduced into the column reactor to be brought into contact with the asymmetric catalyst particles, to thereby convert the compounds to an optically active ?-aminocarbonyl compound. The preferable asymmetric catalyst particles are resin particles that are prepared from a monomer composition containing a proline derivative monomer having an unsaturated bond and a radical polymerization initiator, and that act as a catalyst for an asymmetric Mannich-type reaction.

  • Patent number: 8445621
    Abstract: A novel polyimide resin is formed by imidizing a diamine component including an amide group-containing siloxane diamine compound represented by the following formula (1) and an acid dianhydride component including an aromatic acid dianhydride such as 3,3?,4,4?-diphenylsulfone tetracarboxylic dianhydride. This novel polyimide resin utilizes a novel polyimide resin into which a reaction group capable of reacting with a crosslinking agent to form a crosslinking point is pre-introduced before imidization. The novel polyimide resin can confer a comparatively low elastic modulus and heat resistance to a dry film or a photosensitive cover film formed from a photosensitive polyimide resin composition containing the novel polyimide resin. In the formula (1), R1 and R2 are each independently an optionally-substituted alkylene group, m denotes an integer of 1 to 30, and n denotes an integer of 0 to 20.
